Cameron Siler, Katrina Menard, and the OU field crew (Austin Carriere, Elyse Ellsworth, Sierra Smith & Sam Eliades) arrived safely in Manilla on May 22 and had a day or so to explore the city while waiting for collaborators Dr. Duncan Irschick (UMass-Amherst) and Dr. Phillip Bergman (Clark University). They have now wrapped up collecting at their first site in Cayagan Province on Luzon Island and are now traveling...

As part of the Spring 2015 Herpetology Course (BIOL 4083) taught by Dr. Cameron Siler at the University of Oklahoma, students took part in a semester long, small group writing assignment that formed a large basis of their final course grade. The class was broken up into three groups of seven or eight students, and each group was assigned a distinct lineage of...

Cameron and Nick of the Siler Lab are joined in the Philippines by Sam Noble Museum Invertebrates Curator, Dr. Katrina Menard, University of South Dakota Herpetology PhD candidate, Drew Davis, and Yale University Post-Doc Dr. Oliver Griffith.  All five researchers, plus their Philippine field crew, have spent the last 1.5 weeks in Aurora Province, Luzon Island, Philippines and have collected ~380 herptiles (including...

One of the trickiest aspects of being a graduate student is obtaining funding to conduct new research. Just like an entrepreneur, acquiring funding through fellowships and grants involves convincing others of the importance of your particular research project. This is the case for nearly all funding sources, regardless of size. Recently, I was able to accomplish this goal and receive funding from...

Despite the exceptionally high levels of vertebrate diversity in Southeast Asia, surprisingly little is known about the processes responsible for this occurrence. Recently, an increase in diversity of amphibians has been studied in the Philippines. One genus in particular, Sanguirana, a frog genus endemic to the Philippines, consists of seven species with distinct physical characteristics as well as one or two species...

Recent higher-level frog phylogenetic analyses have included a few members of the endemic Philippine frog genus Sanguirana. Although the monophyly of the group has never been disputed, the recent phylogenetically-supported inclusion of the Palawan Wood Frog (Sanguirana sanguinea) in this clade was highly unexpected. In addition, species boundaries and relationships remain unclear and new species continue to be discovered. We estimate the...

In this paper, a new species of nematode helminth parasite is described: Cosmocerca leytensis. In addition, this paper represents the first descriptive list of parasites found in the gecko, Cytodactylus gubuaot, which is known to reside only on the Leyte Island of the Philippines. Although C. leytensis is the 30th species within the genus, it is the first to be found from...

Cosmocerca leytensis sp. nov. (Ascaridida, Cosmocercidae) from the large intestine of Cyrtodactylus gubaot (Squamata: Gekkonidae) collected on Leyte Island, Philippines is described and illustrated. Cosmocerca leytensis sp. nov. is the 30th species assigned to the genus, the 4th from the Oriental region, and the first from the Philippine Islands. The new species is most similar to those species possessing 4 pairs of...

Recent investigations into the species diversity of false geckos (genus Pseudogekko Taylor) have revealed several cryptic species, highlighting the need for a more thorough understanding of diversity within this enigmatic genus of endemic Philippine geckos. Newly available genetic data reveal that two of the four currently recognized species are complexes of mul- tiple deeply divergent evolutionary lineages. In this paper we evaluate...
